Paducah, Kentucky – Another 1 to 3 inches of rain could overwhelm already soaked ground across southern Illinois, southwest Indiana and northwest Kentucky before daybreak Thursday, raising the threat for flash flooding overnight. Water may quickly cover low-water crossings and urban streets, especially near and north of Illinois Highway 13.
According to the National Weather Service in Paducah, a Flood Watch remains in effect through Thursday morning for much of southern Illinois, including Jackson, Williamson, Saline and Gallatin counties, as well as Vanderburgh, Warrick and Spencer counties in Indiana and Henderson and Daviess counties in Kentucky. Training showers and thunderstorms are expected to redevelop this afternoon and persist into the night. Rainfall totals could climb 1 to 3 inches on top of the 1 to 2 inches that fell Wednesday morning.
Communities such as Carbondale, Marion, Evansville, Owensboro and Mount Vernon face the highest risk for rapid runoff in poor drainage areas. Small creeks and streams may rise quickly if storms repeatedly move over the same neighborhoods.
Residents should monitor alerts closely and be ready to act if Flash Flood Warnings are issued. Never drive across flooded roadways. The flood threat will remain elevated until the rain tapers off Thursday morning.
